Quick and dirty, zeroed 1" high at 100 yards like a varmint rifle might be...
50 V-Max at 3600, then 75 A-Max at 3050:
300 -6" -8"
400 -19 -22
500 -42 -43
600 -80 -73
700 -140 -116
800 -227 -172
900 -348 -247
1000 -506 -345
If you jack the 50 up to 22-250 velocities and stop counting at mid-range, you can make the 50 look flatter. But you don't buy long, pointy bullets to stop shooting at 500 yards.
It's true, you don't buy long bullets to stop at 500. But I wonder about those numbers. The Pact Pro has a ballistic program built in. Running the two identically and changing only BC and velocity, mine come out very different.

Those .223 case velocities aren't jacked up, they're accuracy, everyday loads through a Shilen/223 and a Schneider/223AI, both 14twist.....IMI brass, AA2015 and VV133 powder.
The 223AI chamber has 0 freebore, 1.765" long - .010" past case length, .250"nk.
I don't normally pay attention to COAL, but with 50VMax seated to lands it's 2.262" overall. You have quite a bit of freebore, shooting longer bullets you need it.
A 60VMax is .120" past the neck/shoulder and down into the case. I've no 75's and don't know how far down they'd seat. These guns usually shoot either TNT's or BlitzKings, mostly BK's. Depends on what the targets will be. The BK/BT/Vmax have better BC. At the lands a TNT seats only .110" into the neck, a BK goes about 2/3 way down.....that's with no freebore. Add freebore to get a 60VMax all the way up into the neck and the TNT wouldn't come close to finding any lands. The BK would be way out there. Long freebore with 40's there'd be no hope and going 4100-4200 those things shoot real flat.
Those numbers up there are drop only. I've never said lighter bullets are for longer distances or that they handle the wind as well.....I don't care to shoot varmints at even 500yds with a 223 cased round. I'm just questioning your numbers. And as I said before, people shoot what they want it doesn't matter. There's no one right way, even though some like to make everything into a mine's-better-than-yours-I'm-smarter-than-you pissing match.
